MOTOR VEHICLE TRAFFIC SIGNAL WINDOW Filed Jan. ll, 1932 Patented May 16, 1933 UNITED STATES PATENT OFFICE MOTOR VEHICLE TRAFFIC SIGNAL WINDOW Application led January 11, 1932. Serial No. 585,906.

Our invention relates to motor vehicle traffic signal windows and certain objects of the invention are to provide a windo-w for automobiles comprising a stationary and a pivotally mounted glass plate adapted to be yieldingly closed and whereby the pivotally mounted plate may be pushed outwardly by one movement olf the drivers hand with which the traflic signal is instantly given.

Further objects are to provide a window that is water tight and which may be kept closed to exclude the cold and which may be in stantly opened when it is desired to give a trafllc signal. A still further object is to provide novel means for yieldingly retaining` the window in the closed position.

With the above and other objects in view which will appear as the description proceeds, the invention consists of the novel construction, adaptation, combination and arrangement of parts hereinafter described and claimed. These objects are accomplished by devices illustrated in the accompanying drawing; wherein: Figure 1 is a general View in side elevation showing the window installed in an automobile; Fig. 2 is a detail view in horizontal section taken substantially on a broken line 2-2 of Fig. 3; Fig. 3 is a view partly in side elevation and partly in vertical section of the window; Fig. -l is a view in vertical section taken on a broken line 4-4 of Fig. 3; Fig. 5 is a view in vertical section taken substantially on a broken line 5-5 of Fig. 6; Fig. 6 is a view in perspective of a sash bar member and a channeled clamp sash member; and Fig. 7 is a de tail view 1n horizontal section taken on a broken line 7 7 of Fig. 3.

Referring to the drawing throughout which like reference numerals indicate like parts, the numeral 5 designates a channeled window Jframe which is secured in a motor vehicle door in the usual manner and extends downwardly into the door below the window opening so that the window may be lowered in the regular manner if desired. Slidably disposed within the channels of said frame are a pair of channeled sash members 6 whose lower ends are secured at 7 to a base bar 8 which retains said sash members in spaced apart relation within the frame. The glass is made in two pieces; namely an upper plate 9 and a lower plate 10. The upper plate occupies substantially two-thirds of the window opening and its lateral edges are y'held 55 stationary by the channeled sash members 6 `with felt strips 11 interposed therebetween as shown in detail in Fig. 7.

Immediately below the upper glass plate 9 blocks 12 are mounted within the chan- '60 neled sash members 6 by means of pivots 18. The upper ends of channel bars 14.- are secured to said blocks with their flanges fitting into the channeled sash members as shown y Y in Fig. 2. Each of said channeled sash mem- :05 bers is provided with an outwardly projecting flange. 15 whose lower portions are out and bent inwardly to provide stops 16 which retain the pivotally mounted channel bars 14: against excessive outward pivotal movement. 70 A spring 17 is interposed between the lower ends of said channel bars and channeled sash members and said springs normally retain the channel bars outwardly against said stops 16.

The lower glass plate 10 is securely held between channeled clamp sash members 18 with felt interposed therebetween. `The upper ends of said clamp sash membersl are provided with laterally projecting pins 19 which 80 pivotally fit into holes 2O extending through the channel bars 14 and into the blocks'lQ. The side edges of the channel barsare raised to form longitudinal bulges 21 that taper outwardly from the top to the bottom as most B5 clearly shown in Fig. 6. And the channeled clamp sash members 18 have centralbulges 22 along their side faces. Thus, when the lower glass plate 10 is moved to the closed position said bulges7 in pressing against the 90 tapered bulges 21, depress the channel bars 14 against the springs 17 and snap over the bulges 22 whereby the lower glass plate as a whole is yieldingly but firmly retained against the projecting flanges 15 of the channeled sash members 6. f

By means of the foregoing described arrangement when the lower glass plate 1U is closed same may be pushed outwardly by one 100 movement of the drivers hand with which the tralic signal is then instantly given. The window may then be promptly closed or same may pivotally drop to the closed position by its own weight. It will now be apparent that we have provided means whereby traftic siglnals may be readily given without having to keep windows constantly open to admit the cold' or without the necessity of having to slidably open the window as in present practice. In Fig. l of the drawing it will be noted that the lower edge of the stationary glass plate 9 and the upper edge of the pivotally mounted glass plate lO are correspondingly beveled outward, as at 23, for the purpose of excluding rain walter, and the upper edge of the base bar 8 is provided with a flanged rubber strip 24 that is adapted to receive the lower edge of the lower glass plate in the closed position whereby rain water is l2() likewise excluded.

Having thus described our invention, it beingunderstood that minor changes in its construction and arrangement may be resorted to without departing from the scope and .25 Spirit of the invention, what we claim and desire to secure by Letters Patent of the United States is A motor Vehicle traflic signal window having in combination a frame, a pair of chan- '30 neled sash members slidably mounted within the frame, a base bar fixed to the lower ends of said sash members, an upper glass plate mounted stationary in the sash members, a pair of channel bars having their upper ends Qpivotally mountedA within the channel sash members immediately below the upper glass plate, said channel bars tapering outwardly from top to bottom, stops for thelower ends of said channel bars, springs adapted to nor-. 40 Inally retain the channel bars outward against thestops, a lower glass plate, channel clamp sash members lixed to the lateral edges of said lower glass plate, outwardly projecting flanges for the channel sash members, and the upper ends of said channel sash clamp menibers ,pivoted tothe upper ends of the channel bars whereby the lateral edges of the channel clamp sash members are adapted to snap over the tapering edges of the channel bars when the lower glass plate is moved to the closed position and whereby the clamp sash members are Aretained against the outwardly projecting flanges of the channel sash members by the spring expanded channel bars. In testimony whereof we aflix our signatures.
